the tabletop role-playing gaming industry started out by trying to model the methods of traditional publishing, found out the hard way that that really didn’t work for them (in the long run, it’s not working for big publishers either, but they’re BIG, so they didn’t notice as soon), and had to find new solutions. They were the first to adopt electronic publishing, shame-free POD printing, electronic-only publishing, podcasting-modules, mixed media releases, and every other experimental method anyone could think of, good or bad. That’s fine: they’re small, and experimenting is something small groups of people can DO that big groups can’t.
